WATER-CLOS ET VALVE.

SPECIFICATION forming part of Letters Patent No. 326,528, datedSeptember 15, 1885.

Application filed July 2, 1885. (No model.)

To all whom it may concern:

Be it known that LEARNEs'r A. STRAAT, a citizen of the United States,residing at Jersey City, in the county of Hudson, State of New Jersey,have invented a new and useful Improvement in Water- Closet Valves: ofwhich the following is a full, clear. and exact description, referencebeing had to the accompanying drawings, making part of thisspecification, in which- Figure 1 is a perspective view of a waterclosetseat with my improvements attached. Fig. 2 is a side elevation of thesame. Fig. 3 is a horizontal section through :10 w of Fig; 2. Fig. 4 isa vertical section through 3/ y of Fig. 1.

My invention relates to water-closet apparatus designed for theprevention of any possible escape of sewer-gas, and to secure anautomatic action of the overflow and the closing of the discharge-valve;and it consists of the combination of devices hereinafter explained andclaimed.

In order to enable others skilled in the art to make and use myinvention, I will proceed to describe the exact manner in which I havecarried it out.

In the drawings, A represents the bowl of the closet with a vertical ordownward passage, B, in which I place the cut-off valve 0, operated bythe lever D, attached to the cross-arm E, said arm having abearing-surface or fulcrum, a, against which the lever abuts. To theopposite end of the arm E is secured the spring F, which, when theleverarm is released,automatically closes the valve.

By this construction the contents of the bowl fall by gravitation, andinstantly the valve is again closed, so as to prevent any possibleescape of the sewer-gas.

In the act of opening the valve by pressing down the lever D and raisingthe rear end of the arm E the chain or cord G is drawn, which opens thevalve in the tank H and allows a free flow of water in the bowl duringthe whole time the cut-off valve is open. It

is evident that the same result will be produced by simply raising orpulling up the lever, which in turn would pull the chain G and open thevalve in the tank.

From the bowl A passes the overflow-pipe H to the automatic attachmentI, which is constructed with a float-valve, J, having a guide-rod, K, tokeep it in its proper position. When an overflow from the bowl takesplace, the water raises the float-valve J until it passes above theopening of the discharge pipe L, when the water passes into and down theventilator-pipe M. When the water has been discharged, the float againsinks below the opening in the pipe L, and automatically closes thewasteway.

To guard against the upward pressure of gas below the bowl, I connectthe downward passage B, at a point below the cut-off valve 0, to theventilator-pipe M, by means of the pipe N. I thus lead any gas which maycollect below the bowl through the ventilator into the open air, andprevent its possible escape into the building.

To avoid possible damage to the arm E when the lever is released and thespring Fis allowed its play, I provide the stop 0, and cushion it withrubber or other elastic packing P, to reduce the shock produced by theforce of the spring F to its minimum.

Having thus explained my invention, what I claim as my invention, anddesire to secure by Letters Patent, is-

1. The combination, with the bowl, the tank, and the valve, of the armE, having a bearing or fulcrum, a, and a lever, D, pivoted to the end ofthe arm and bearing against the fuleruma, said lever extending upwardlyand forward, whereby the valve in the tank and the cut-off valve areautomatically and simultaneously opened by depressing said lever,substantially as herein .described.

2. The bowl, the vertical passage, the cutoff valve, and the arm E, incombination with an upwardly-extending lever,-D, pivoted to the arm, andbearing against the fulcrum a on the same, a stop, 0, a packing on thestop, a chain, G, connected to the short arm of the lever and to thevalve in the tank, whereby when the lever is depressed the valve in thetank is opened and the cut-off valve rotated until its opening comes inline with the passage B, and a spring engaging the arm and closing bothvalves simultaneously, substantially as herein described.
